Application filed September 10, 1914.

To all whom it may concern Be it known that T, CARRIE M. NoRwooD, of Avon, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Sash-Curtain Rods, of which the following is a specification.

This invention relates to rods to be attached horizontally to window frames or casings for the purpose of supporting a sash curtain at the inner side of the window.

The invention has for its object to provide a simple and inexpensive sash curtain rod or support which is adjustable in length to accommodate window casings of various widths and is composed of separable parts adapted to be readily assembled anddisconnected.

The invention consists in the improvements which I will now proceed to describe and claim.

Of the accompanying drawings forming a part of this specification: Figure 1 represents a top plan view of a curtain rod embodying my invention engaged with a window casing, the latter being shown'in section; Fig. 2 represents an enlargement of a portion of Fig. 1, shown partly in section; Fig. 3 represents a plan view of a portion of one of the members of the rod; Fig. 4 represents a fragmentary view showing a slight variation from the connection shown by Fig. 2.

The same reference characters indicate the same or similar parts in all the views.

My improved curtain rod is composed of two independent straight wire end members 12, 12, composed of relatively stiff wire, and an intermediate member 13 composed of resilient wire coiled to form an elongated helical spring which constitutes a contractile connection between the end members. The members 12 and 13 are detachably connected preferably as hereinafter described, the length of the member 13 being such that when said member is normally contracted the total length of the rod is less than the distance between the outer edges of the vertical members 14 forming the inner side of a window casing. The rod is therefore extensible by the elongation of the member 13 so that the rod may be adapted to casings of different widths.

The outer end of each member 12 is pro- Specification of Letters Patent.

vided with a hook 15, said hooks being formed and arranged to enter the outer edges of the casing members 14, as indicated by Fig. 1, the form and arrangement of the hooks being such that they are held by the contraction of the member 13 in engagement with the casing members 14.

- The hooks 15 are preferably formed on end portions bent from the straight body portions of the members 12, said end portions being bent to form shoulders 16 located between the straight portions of the members 12 and the hooks 15 and adapted to bear on the outer faces of the casing members 14 so that the straight portions of themembers 12 are offset from the casing members 14, as indicated by Fig. 1. A sash curtain supported by the rod is therefore adapted to be adjusted to extend practically across the faces of the casing members 14.

As above stated, the members 12 and 13 are detachably connected so that the rod may be reduced to compact form for storage and shipment by separating the said members, and may be engaged with a pocket or casing on the upper edge of a sash curtain by inserting one of the members 12 in said pocket or casing and bunching the curtain an said member before assembling the memers.

In the embodiment of my invention here shown I utilize the end convolutions of the helical member 13 as internal screw threads, the inner ends of, the members 12 being bent backwardly to form hook-shaped coupling parts or loops 12 provided with notches 16 which constitute the equivalent of an external screw thread, as indicated by Fig. 2, which shows some of the convolutions of the member 13 in section and engaged by a screwing action with one of the coupling parts 12*.

It will be seen that the members 12 and 13 may be connected and disconnected by a rotary movement of either member relatively to the other. When the members 12 and 13 are connected the coupling parts 12 are covered by the ends of the member 13 so that they are not liable to engageand tear the curtain.

The described curtain rod is free from liability to accumulate dust, particularly at the portions which are not covered by the curtain.

When the members are disconnected they may be packed in small compass side by side.

It will be seen that the width of the hookshaped coupling part or loop 12 is such that said part is slightly wider than the internal diameter of the convolutions of the member 13, so that the end convolutions of the member 18 closely hug the part 12 and are engageable therewith by a screw-like action.

Fig. 4 shows a modification in which the coupling part 12, instead of being provided with notches 16, is provided with a single spur 16 formed to engage the helical groove between two adjacent convolutions of the member 13, the part 12 having in this case the well known form of a shepherds crook. The spur 16 is an equivalent of the notches 16 as a means for engaging the convolutions of the member 13 by a screw-like action.

Havingdeseribed my invention, I claim 1. A sash curtain rod composed of two independent straight wire end members having inwardly offset casing-engaging hooks at their outer ends, and an intermediate resilient member formed as a helical spring engaged with the inner end portions of the end members and constituting a contractile connection between said end members adapted to hold said hooks in engagement with outer edge portions of a window casing.

2. A sash curtain rod composed of two in- Copies of this patent may be obtained for dependent wire end members each having a straight elongated body portion and a bent outer end portion including an inwardly oliset casing-engaging hook and a shoulder formed to bear on the face of a window casing and hold the straight portion spaced therefrom, and an intermediate resilient member formed as a helical spring detachably engaged with the inner portions of the end members and constituting a contractile connection between said end members adapted to hold the said hooks in engagement with outer edge portions of the casing.

3. A sash curtain rod composed of a resilient member formed as a helical spring, and two independent straight wire end members having casing-engaging means at their outer ends and bent inner ends forming loops of greater width than the internal diameter of the spring convolutions and adapted to closely fit within the end convolutions of the resilient member, said loops having means for engaging said convolutions with a screwlike action.

In testimony whereof I have aliixed my signature, in presence of two witnesses.
